Skeletal Muscle Myofibrillar Protein Abundance Is Higher in Resistance-Trained Men, and Aging in the Absence of Training May Have an Opposite Effect

Sports, 2020
Resistance training generally increases skeletal muscle hypertrophy, whereas aging is associated with a loss in muscle mass. Interestingly, select studies suggest that aging, as well as resistance training, may lead to a reduction in the abundance of ...

Degradation of myofibrillar proteins by cathepsins B and D [PDF]

Biochemical Journal, 1977
1. The procedure of Barrett [(1973) Biochem. J.131, 809–822] for isolating cathepsins B and D from human liver was modified for use with rat liver and skeletal muscle. The purified enzymes appeared to be similar to those reported in other species. 2.

Physicochemical characteristics of fish myofibrillar and sarcoplasmic proteins treated at various pH conditions [PDF]

Protein solubility of Pacific whiting muscle with isoelectric point at pH 5.5 was significantly affected by pH. The highest breaking force was measured from fish proteins treated at pH 11, while high deformation values were obtained at pH 2 and 11 ...

Ultrastructure of longissimus dorsi myofibrillar proteins and heat-induced gels as observed with atomic force microscopy: effects of pH values and sodium ions

International Journal of Food Properties, 2019
Water holding capacity, texture characteristics, and qualitative structural properties had been mainly focused on heat-induced gelation of myofibrillar proteins; however, the quantitative analysis to ultrastructure of the proteins and heat-induced gel ...

Proteomics Analysis of the Regulatory Mechanism of the Calcium-Independent Phospholipase A2 Activity of Peroxiredoxin 6 on Beef Tenderization [PDF]

Shipin Kexue
To elucidate the effect of the calcium-independent phospholipase A2 (iPLA2) activity of peroxiredoxin 6 (Prdx6) on beef tenderization and the underlying mechanism of action during the postmortem aging process, we investigated the specific role of Prdx6 ...

Chemical oxidation decreases proteolytic susceptibility of skeletal muscle myofibrillar proteins

, 2006
The objective of this study was to investigate the effect of chemical oxidation on proteolysis susceptibility of myofibrillar proteins. Myofibrils were prepared from pig M. longissimus dorsi and oxidised by a hydroxyl radical generating system.

Effect of Interaction between Mealworm Protein and Myofibrillar Protein on the Rheological Properties and Thermal Stability of the Prepared Emulsion Systems

Foods, 2020
In this study, we investigated the effect of replacing myofibrillar protein (pork ham) with edible insect proteins (Tenebrio molitor L.) in meat emulsion systems and examined the interaction between the two types of proteins.

ZER1 Restrains Pressure Overload‐Induced Cardiac Remodeling by Targeting DVL2 for Gly/N‐Degron‐Dependent Degradation

Advanced Science, EarlyView.
Pressure overload suppresses cardiomyocyte ZER1, weakening CRL2Zer1‐mediated DVL2 degradation and allowing DVL2 accumulation. Elevated DVL2 activates CaMKII‐HDAC4‐MEF2C signaling, drives fetal gene reactivation, and promotes pathological remodeling.

Characterizing the Catalytic Action of μ-Calpain on Myofibrillar Protein Structure [PDF]

, 2006
Solving the problem of inconsistent meat tenderness is a top priority of the meat industry. This requires a greater understanding of the processes that affect meat tenderness and the adoption of such information by the meat industry. It is essential that

Oxidation of Myofibrillar Proteins in Human Heart Failure

Journal of the American College of Cardiology, 2011
We investigated the incidence and contribution of the oxidation/nitrosylation of tropomyosin and actin to the contractile impairment and cardiomyocyte injury occurring in human end-stage heart failure (HF) as compared with nonfailing donor hearts.Although there is growing evidence that augmented intracellular accumulation of reactive oxygen/nitrogen ...
